Documentation Style Used in this Guide

Most of the steps documented in this tutorial describe an environment consisting of two nodes (node-a and node-b). Examples of user command execution are shown within the guide. The sections below show the styles used to indicate the different nodes or users used to execute commands.

Nodes to Execute Actions

When a particular set of command needs to be executed on a specific node, the prompt contains the user-name & host-name as follows:

An in-line comment similar to the below will also be shown:

*You need to execute the following steps on the primary node (node-a).

If the name of the node is not specified in the prompt, those commands need to be executed on both nodes (see the following example):

An in-line comment similar to the below will also be shown:

*You need to execute the following steps for each node.

Users to execute commands

Within the guide, the user who executes the command is identified by the prompt used.

If the command is executed as a regular user (e.g., ec2-user for most of the EC2 Instances), the prompt is shown as:

Once you become the root user, the prompt is described as #

If a specific user needs to execute a command, the name of the user is included in the prompt as follows:

Option to Select while Working with the SIOS GUI (Wizards)

One of the benefits of using LifeKeeper is that wizards scan the system and then provide suggested values within the installation screens. In most cases, it is only necessary to confirm and select the default values. Where default values may be chosen, the guide indicates them with a checkmark . If no checkmark is shown, a specific value (such as an environment-specific IP address) may need to be entered.

When modifying any parameters given in the guide (e.g., choosing a different resource name, different IP address, etc.), care must be taken to use the updated values for each occurrence of the parameters after they are introduced.
